Key Features

++

Description

++

  • Failure of the body to provide defense against bacterial or viral invasion as there is no or insufficient production of antibodies

  • There are 70 to 100 types in approximately six categories

  • Primary immunodeficiency disorders

  • Congenital immunodeficiency diseases

  • B-cell (antibody) deficiencies

  • T-cell deficiencies

  • Combination B- and T-cell deficiencies

  • Defective phagocytes

  • Complement deficiencies

  • Unknown (idiopathic)

  • Severe combined immunodeficiency (SCID) (bubble boy disease) is considered the most severe form of the disease

    • Chronic infections

    • Frequent infections

    • Multiple body-system involvement

    • Onset often vague with misdiagnosis of underlying disease

++

Essentials of Diagnosis

++

  • Must be made by a physician and confirmed by medical diagnostic testing

  • Warning signs of primary immunodeficiency

    • Eight or more new ear infections within one year

    • Two or more serious sinus infections within one year

    • Two or more months on antibiotics with little effect

    • Two or more pneumonias within one year

    • Failure of an infant to gain weight or grow normally

    • Recurrent, deep skin or organ abscesses

    • Persistent thrush in mouth or elsewhere on skin, after age one

    • Need for intravenous antibiotics to clear infections

    • Two or more deep-seated infections such as sepsis, meningitis, or cellulitis

    • A family history of primary immune deficiency

  • Frequent/recurrent Infections

  • Blood infections

  • Inflammation of internal organs: liver, spleen, pancreas

  • Autoimmune disorders

  • Blood disorders

  • Digestive problems

  • Delayed growth and development

  • Genetic factors

  • Abscessed wounds

  • Ineffective use of antibiotics
